Oh yeah. I am very familiar with it. No one ever considers these physics when they are going 85 plus. “Well if I wreck it will be at only 85.” Not if it is a vehicle also doing 85 towards you, that is the combined speed of 170 Mph... And same at lower speeds “I’m only going 35” yeah but so is that vehicle headed at you and the impact is going to be a 70 Mph impact for both.
